Our Abpromise guarantee covers the use of ab82935 in the following tested applications.

The application notes include recommended starting dilutions; optimal dilutions/concentrations should be determined by the end user.

Application Abreviews Notes
ICC/IF Use a concentration of 5 µg/ml.
WB Use a concentration of 1 µg/ml. Predicted molecular weight: 59 kDa. Good results were obtained when blocked with 5% non-fat dry milk in 0.05% PBS-T.
ELISA Use at an assay dependent concentration.

Titre using peptide based assay 1/12500.


  • FunctionHydrolase that deubiquitinates monoubiquitinated target proteins such as histone H2A and H2B. Required for proper progression through S phase and subsequent mitotic entry. May regulate the DNA damage response (DDR) checkpoint through deubiquitination of H2A at DNA damage sites. Associates with the chromatin.
  • Tissue specificityExpressed in all tissues examined, with strongest expression in pancreas.
  • Sequence similaritiesBelongs to the peptidase C19 family. USP3 subfamily.
    Contains 1 UBP-type zinc finger.
  • DomainBoth protease activity and an intact zinc finger are required for H2A monodeubiquitination.
  • Cellular localizationNucleus. Localizes preferentially with monoubiquitinated H2A to chromatin.

Anti-USP3 antibody images

  • ICC/IF image of ab82935 stained HeLa cells. The cells were 100% methanol fixed (5 min) and then incubated in 1%BSA / 10% normal goat serum / 0.3M glycine in 0.1% PBS-Tween for 1h to permeabilise the cells and block non-specific protein-protein interactions. The cells were then incubated with the antibody ab82935 at 5µg/ml overnight at +4°C. The secondary antibody (pseudo-colored green) was Alexa Fluor® 488 goat anti- rabbit (ab150081) IgG (H+L) preadsorbed, used at a 1/1000 dilution for 1h. Alexa Fluor® 594 WGA was used to label plasma membranes (pseudo-colored red) at a 1/200 dilution for 1h at room temperature. DAPI was used to stain the cell nuclei (pseudo-colored blue) at a concentration of 1.43µM for 1hour at room temperature.

    Predicted band size : 59 kDa
    Observed band size : 65 kDa (why is the actual band size different from the predicted?)
    Additional bands at : 38 kDa. We are unsure as to the identity of these extra bands.

Thank you for your reply.

Either of these antibodies should work well in your assay. Ab101473 has already been tested with HeLa lysates and works well, however I know that the exposure time was an important variable in your decision. Since th...

Thank you again for your patience.

I have heard back from the lab that this antibody was also tested with 721_B lymphoblasts, which have been shown to express USP3.

I hope this information will be useful, but please let me know if y...

Thank you for your call last week and for your patience whileI have been in touch with the lab.

The exposure time used to create this image was 1 minute. We are lookingthrough our files to see if the antibody has been tested with other cell l...
